Philips MSR Gold 575 SA/2 DE - Metal halide lamp 575 W, 7,500 K, SFc-11 base (double terminal)
The Philips MSR Gold 575 SA/2 DE is a double-ended (SFc-11) metal halide HID lamp designed for professional entertainment applications in moving heads and effects projectors. Its short-arc (5.0 mm) architecture produces a highly focused beam with a color temperature of 7,500 K and a CRI of 70 , delivering bright, white light with excellent visual impact. The MSR Gold™ SA Double Ended series incorporates gold-plated caps and Philips' P3 technology to enable higher operating temperatures , minimizing premature lamp and socket failures and maintaining consistent performance throughout its 750-hour lifespan . It provides a nominal luminous flux of 41,000 lm , operates in a universal position , and is not dimmable .

Product benefits
-
Stable performance over time: P3 + gold caps for less thermal fatigue and fewer shutdowns.
-
Powerful, high-contrast beam: the 5mm arc focuses the light for impactful beams and crisp gobos.
-
Professional integration: SFc-11 format and standard dimensions widely used in 575W luminaires.
-
Uniform cool color: 7,500 K with consistent color printing in the MSR range.
Use cases
-
575W moving heads (beam/spot/wash) and effects projectors with SFc-11 socket.
-
Theatre, concerts, festivals and events that require high intensity and quick replacement.

Rental and touring where reliability and color consistency reduce operating costs.
Frequently Asked Questions
-
Is it dimmable? No; this lamp does not support dimming with a conventional dimmer. Use the specified HID fitting.
-
What does “198 V” mean? It is the minimum ignition voltage of the equipment (ballast/igniter). The lamp is specified by wattage and current (575 W, 7 A).
-
In what position can it work? Universal , in any orientation.
